Why CoreOS?

CoreOS has become the preferred distro for Docker. You can download the Stable ISO

Why Veertu?

Like xhyve, Veertu takes advantage of the Hypervisor.framework that was introduced in OS X 10.10, which brings Type 1 hypervisor technology (direct, host-level access to hardware) to OS X. You can download it in the CloudFront

1. Start the CoreOS image.

   • Set a password for user core

   core@localhost ~ $ sudo passwd core
   

2. Get the ip address

   core@localhost ~ $ ip route
   default via 192.168.64.1 dev ens3  proto dhcp  src 192.168.64.X  metric 1024 
   172.17.0.0/16 dev docker0  proto kernel  scope link  src 172.17.0.1 
   192.168.64.0/24 dev ens3  proto kernel  scope link  src 192.168.64.X 
   192.168.64.1 dev ens3  proto dhcp  scope link  src 192.168.64.X  metric 1024
   

3. Ssh into CoreOS

   ssh [email protected] -q -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no
   

4. Install CoreOS

   • Get your public SSH key

     cat ~/.ssh/id_rsa.pub
     

   • Generate a crypted password

     openssl passwd -1
     

   • Create a cloud-config.yml file to upgrade CoreOS, add your ssh key and open the docker socket when CoreOS starts:

     core@localhost ~ $ vi cloud-config.yml
     

     #cloud-config
     
     users:
       - name: core
         passwd: # paste your a crypted string to here
         groups:
           - sudo
           - docker
         # include one or more SSH public keys
         ssh-authorized-keys:
           - # paste your a public SSH key to here
     
     coreos:
       units:
         - name: docker-tcp.socket
           command: start
           runtime: no
           content: |
             [Unit]
             Description=Docker Socket for the API
             [Socket]
             ListenStream=2375
             Service=docker.service
             BindIPv6Only=both
             [Install]
             WantedBy=sockets.target
     
         - name: docker.service
           command: start
     

   • Install the CoreOS to /dev/sda with our cloud config:

     core@localhost ~ $ sudo coreos-install -d /dev/sda -c cloud-config.yml
     core@localhost ~ $ sudo reboot
     

5. Usage and check

   • Set the docker host

     export DOCKER_HOST=tcp://192.168.64.X:2375
     

   • Check if it works

     docker info
     

6. Sharing folder on your Mac

   • Install Add-ons.

     brew install ssh-copy-id osxfuse sshfs
     

   • Auto Login without a password.

     ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected] -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no
     

   • Mount remote file systems over ssh.

     id -P <username>
     <username>:********:<uid>:<gid>::0:0:Mimosa:/Users/mimosa:/usr/local/bin/fish
     

     mkdir -p ~/Documents/veertu
     sudo sshfs -o allow_other,defer_permissions,reconnect,uid=<uid>,gid=<gid>,volname=veertu [email protected]:./ ~/Documents/veertu
